The Seven Crystal Balls: Part 2 - S3-E4
Revealing mistake: When the detective is phoning the police about the black sedan, a man sitting at a desk is writing the details. He is writing on four lines of paper, but after writing the first three lines, he is just writing over the third line for a second time and the fourth line of writing suddenly appears on the paper.

Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
